After Kurusu is stabbed, Takuru infiltrates AH Tokyo General Hospital, hoping to find the creator of the sumo stickers.  When he gets there, he, Onoe, and Itou are forced to hide in the basement to avoid being spotted.  Inside the basement's autopsy room, they find a secret entrance that leads to an underground laboratory where terrible experiments were once conducted.  Takuru thinks he's been here before...
It's too late now to be crying about leaving.
،حتّى لو بكيتُم راغبين بالعودة
فاتَ الأوان الآن
Jetzt gibt’s kein Zurück mehr,
auch wenn du noch so sehr quengelst.
Es demasiado tarde para volver atrás.
Ahí es adonde me dirigía.
Es demasiado tarde para volver atrás.
Ahí es adonde me dirigía.
Il est trop tard
pour faire demi-tour.
È troppo tardi per piagnucolare
che volete andarvene.
Já é tarde demais, mesmo
 que queiram voltar.
